Linux 下安装Redis
下载地址：http://redis.io/download，下载最新稳定版本。
一、本教程使用的最新文档版本为 2.8.17，下载安装包：
新建目录：
mkdir /usr/local/redis
cd /usr/local/redis/
下载地址： wget http://download.redis.io/releases/redis-2.8.17.tar.gz
如下：
[root@instance-38r7isl1 /]# mkdir /usr/local/redis
[root@instance-38r7isl1 /]# cd /usr/local/redis/
[root@instance-38r7isl1 redis]# wget http://download.redis.io/releases/redis-2.8.17.tar.gz

[root@instance-38r7isl1 redis]#
二、解压安装包：
[root@instance-38r7isl1 redis]# tar -vxzf redis-2.8.17.tar.gz
三、make命令编译
注：如果出现下面错误：
[root@instance-38r7isl1 redis-2.8.17]# make
cd src && make all
make[1]: Entering directory/usr/local/redis/redis-2.8.17/src' rm -rf redis-server redis-sentinel redis-cli redis-benchmark redis-check-dump redis-check-aof *.o *.gcda *.gcno *.gcov redis.info lcov-html (cd ../deps && make distclean) make[2]: Entering directory/usr/local/redis/redis-2.8.17/deps’

[root@instance-38r7isl1 redis-2.8.17]#
安装c++的编译器； 执行 yum -y install gcc-c++
yum -y install gcc-c++
执行make MALLOC=libc命令
make MALLOC=libc
显示成功：

CC redis-cli.o
LINK redis-cli
CC redis-benchmark.o

Hint: It’s a good idea to run ‘make test’ ??

修改redis.conf配置
daemonize yes
requirepass 123456
设置Redis自启动，新建配置文件redis
[root@instance-38r7isl1 redis-2.8.17]# vi /etc/init.d/redis

设置文件权限和启动Redis服务并设置开机启动

[root@instance-38r7isl1 init.d]# /etc/init.d/redis start
